• Protaeti pryeri, a scarab beetle from the subfamily Cetoniinae (Coleoptera, Insecta), was recently found at Port of Tokyo Wild Bird Park, nature preserve located on reclaimed land in Tokyo, Japan. As this species originates from the Nansei Islands in southern Japan, and is not native to the Tokyo area, it is referred to as a “domestic alien”. Two additional domestic alien Cetoniinae species (Cetonia pilifera, P. brevitarsis) may have been observed in the park. If any of these species expands their range from the coast to inland Tokyo, severe ecosystem disturbance and genetic introgression could occur. We investigated the prevalence and resource use of five Cetoniinae species in the park. We found high numbers of P. pryeri adults and larvae. In the soil layer, where a lot of larvae were particularly abundant, their excretions tended to replace the soil itself. This phenomenon may negatively affect the soil ecosystem and alter decomposition. In addition, abnormal outbreaks of adult Gametis jucunda, C. pilifera, and P. brevitarsis, as well as P. pryeri, were found on flowers and tree saps from multiple plant species. Continued monitoring, rearing them, and DNA-based research are recommended in order to manage the spread of domestic alien Cetoniinae species.
